I think you forgot something... like
- how are these rare metals gained, that made these „imaginative“ vehicles possible?
- and how many people lost theire health or life for it?!
- how much gas was used to produce these cars (as already written down here, energy is still based on gas)
- this car won‘t make you more happier
- neither mars will!
Science developement ist faster than mankind can understand conditions and effect on humans or earth.
I live in a forest and wood mangement area, I can see daily what damage these great vehicles are doing, which were devoloped in the past. And yes they are fast and efficient! Even faster and more efficient than nature is able to recover. Horses have done the job way better, but it was too inefficient for the people, right? Haha
